I need help in coding for the third level of a facet injection. The dr injected levels T10-T11, T11-T12, and T12-L1. I know the first two codes would be 64490 and 64491 but am unsure of the third level. The CPT introduction states to use 64493 for level T12-L1. But would this be true in this case?
Thanks.
Thanks.
